The first para, in which the line you have highlighted says AEW, meaning Airborne Early Warning, not AESA. Even this source says to be less capable then then Chinese AESA ones. So if its less capable one for export markt, it would not be an AESA based.
and as for the second para, again, the writer is comparing KJ-2000 platform with ZDK-03, thus what else to say about what would he be knowing, and if you see the dishes of both platforms, they have different markings, and the prototype of ZDK-03 could be clearly seen with its dish mounted dome at different positions in different pictures, thus the prototype one had a rotating dome, thus it could not be compared with KJ-2000.
Plus, after your highlighted part, the writer says this:
It is somewhat similar to the Saab-2000-mounted Ericsson FRS-890 Erieye system on order from Sweden.
Meaning he is saying it would be a liner shaped configuration, but we saw a dome shaped configuration, thus in my view he is not that much a reliable source or a knowledgeable source. As i had said, people must had and did assumed that since China has AESA based platforms, thus this 3rd would be an AESA based too, many people proved wrong who were advocating that its linear shaped ZDK-03 we are getting and the final product was dome shaped, thus people can make mistakes and this writer made a mistake too.
So dear, there is no reliable enough source which can clarify what the dome has in reality, and as said, my bet (based on my sources) is on PESA for now. Its for sure is an ESA radar.
